Abstract (en)
[origin: EP2853376A1] A composite material comprises of at least first and second layers, each comprising a polymeric matrix material and wound tows (4, 8) for reinforcement. The tows (4, 8) are wound in opposite directions in each of the first and second layers such that overlapping tows form crossover regions (6, 10). The wound tows (8) in the second layer are arranged such that the crossover regions (10) are formed to be laterally offset from the crossover regions (6) in the first layer.
